SAFETY DEVICE FOR GAS-PRODUCERS ADAPTED T0 ACT AS GAS FILTERS, COOLERS,AND DRIERS.

Patented J an. 4, 1921.

Application filed November 14, 1918. Serial No. 262,619.

To all whom it may concern:

Be it known that I, VICTOR LiioN CAzns, citizen of the Republic ofFrance, residing at 128 Rue Perronet, Neuilly-sur-Seine, Seine, in theRepublic of France, have invented new and useful Improvements in SafetyDevices for Gas-Producers Adapted to Act as Gas Filters, Coolers, andDriers, of which the following is a specification.

This invention relates to a safety device acting also as a cooling,filtering and drying apparatus which is adapted to be interposed betweenthe gas producer and the motor on automobiles provided with a gasproducer and by means of which two essential results are obtained asfollows: first, any back firing to the gas producer is prevented bymeans of a bundle of tubes having. a length and a diameter such thatflames are checked thereby and secondly the gases are suitably cooled,filtered and dried before they reach the motor.

The annexed drawing, givenby way of example, is a longitudinal sectionof an apparatus constructed in accordance with the invention.

Referring to the drawing, the apparatus comprises two parallel elongatedcasings B and E arranged one above the other and connected to each otherby means of a tubular bundle T. The upper casing or box, B, is providedwith two necks K and I for the inlet and outlet of the gases. It isclosed at one end by a door A, which has a gas tight joint and carries ahorizontal rod upon which partitions C, C and C are secured. Saidpartitions have a snug fit in the casing and divide the same into threechambers, or compartments a, 6, f The intermediate partition C is cutaway at the top so as to leave a free passage for the gas.

The lower box or casing E is closed at the bottom by a hermeticallyclosing lid F, upon which is secured a vertical partition C whichdivides the casing into two chambers or compartments d and c.

From the upper wall of the lower casing hang two partitions C and Cwhich are cut away at their lower edge and are located in verticalalinement with the partitions G and C in the upper casing A, B, D, O.

Thecompartments or chambers a, 5, f, cl, 8 are filled with a spongiousmaterial g.

The upper and lower casings are connected to each other as alreadyexplained by a bundle of tubes T which are secured at one end to thebottom wall of the upper casing and, at the other end to the upper wallof the lower casing. The length and diameter of said tubes are soselected that any back firingthrough the same is effectively prevented.As shown in the drawing, the tubes T form a connection between thecompartment at and the compartment 01, between the compartment Z) andthe compartments d and e and between the compartment f and thecompartment (2, respectively.

The gas being fed to the apparatus through the neck is enters first thecompartment or in the upper casing and permeates through the spongiousmaterial in said compartment where it is filtered and dried. It thenpasses through the first series or bundle of tubes in which it issubjected to a first cooling, and reaches the compartment d in the lowercasing where it'is filtered and dried a second time by its contact withthe spongious mate.- rial in' the same and so on through all the othercompartments'inboth ca sings and the tubes as indicated by the arrows,the gas being finally discharged at I. The number of tubes T variesaccording to the power of the motor.

A fan or any other similar apparatus V may be used to cool the tubes.

By removing the lid or door A from the upper casing, the rod secured tothe same and the partitions C, C C are pulled out at the same time sothat an eflicient cleaning is effected. In the same manner, by takingoff the lid F from the lower casing the tubes may be easily cleaned. Allthese operations can be effected very rapidly without taking aparteither the piping or the apparatus.

Various details of construction may obviously be modified withoutdeparting from the invention.

Having now described my invention what I claim as new and desire tosecure by Letters Patent is:

1. A safety device for preventing back firing in automobiles providedwith a gas producer, said device comprising in combination an uppercasing, an inlet and an outlet for the gas on said casing, a lowercasing, bundles of tubes aflording communication between the upper andthe lower casing, and means in the upper and lower casings to cause thegases to successively pass through the difi'erent bundles of tubes.

2. A safety device for preventing back firing in automobiles providedwith a gas producer, said device comprising in combination an uppercasing, an inlet and an outlet for the gas on said casing, a lowercasing, bundles of tubes affording communication between the upper andthe lower casing, means for cooling said bundles of tubes and means inthe upper and lower cas ings to cause the gases to successively passthrough the different bundles of tubes.

3. A safety device adapted to act as a filter, a cooler and a drier forthe gas delivered-by a gas producer, said device comprising incombination an upper casing, an inlet and an outlet for the gas on saidcasing, a lower casing, bundles of tubes affording communication betweenthe upper and the lower casing, means for cooling said bundles of tubesand means in the upper and lower casings to cause the gases tosuccessively pass through the difierent bundles of tubes and a filteringand drying medium in both casings.

4. A safety device for preventing back firing in automobiles providedwith a gas producer, comprising in combination an upper casing, an inletand an outlet for the gas on said casing, a door adapted to close saidcasing atone end,means for holding said door in the closed positions, arod secured on said door, partitions secured on said rod and di vidingthe casing into c0mpartments,alower casing, a removable lid adapted toclose said lower casing at the bottom, partitions adapted to divide saidlower casing into compartments, bundles of tubes extending respectivelyfrom one compartment in the upper casing to a corresponding compartmentin the lower casing, some of the said partitions being cut away so as toprovide an uninterrupted passage for the gas from the inlet to theoutlet through all of the difierent compartments and bundles of tubes,successively, means for cooling said bundles of tubes and a filteringand drying medium in the said compartments.

5. A safety device for preventing back firing in automobiles providedwith a gas producer, said device comprising in combination an uppercasing, an inlet and an outlet for the gas on said casing, a lowercasing, bundles of tubes afiording communication between the upper andthe lower casing, means in the upper and lower casings to cause thegases to successively pass through the difierent bundles of tubes and afan adapted to set up a circulation of air about the said tubes.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
